Observed Maxima Timings of RR Lyrae Stars

Many RR Lyrae stars were discovered in globular clusters where they could be used as standard candles for cosmic distance estimations.

There is one issue published by the AAVSO to date. The printed version of the issue contains an introduction, a table of contributing observers, O-C diagrams, and the compiled times of maxima data.

A print copy of this issue is available through our online store. The cost for AAVSO members is $5 and for non-members it is $15.

A Word document version and an ASCII version of this issue may be downloaded free of charge from this web page. The Word version contains all the material in the printed version and the ASCII version has everything except the 0-C diagrams.
